//! ## 梯形图(Trapezoid)
//! 一种受跳表与平衡树启发的新的索引结构,
//! 因其逻辑结构总是表现为梯形, 故称之为"梯形图".
//!
//! - 相对于跳表:
//!     - 不依赖于随机数的概率分布, 结构稳定, 性能稳定;
//!     - 无重复节点, 无空间浪费.
//! - 相对于平衡树:
//!     - 易于理解与实现;
//!     - '读'效率相当, '写'效率占优.
//!
//! ## TZ(Trapezoid)
//! A new created data structure for indexing, a hybrid of 'SkipList' and 'BalanceTree'.
//! Its logical structure always appears as a trapezoid, so it is called "TZ".
//! - Relative to 'SkipList':
//!     - It does not depend on the probability distribution of random numbers,
//!     has stable structure and stable performance;
//!     - No duplicate nodes, no space wasted.
//! - Relative to 'BalanceTree':
//!     - Easy to understand and implement;
//!     - 'Read' efficiency is similar, 'write' efficiency is better.
